Limited access to subscription-based statistical software poses obstacles when students want to apply the skills they acquired in college. Although students may learn programs like SPSS or Stata while at the university, they often find themselves unable to continue using these programs after graduation, making their acquired skills obsolete. As an open-source software program, R offers a solution to this challenge. It is freely accessible to anyone, including students, after they graduate. Therefore, I decided to write a freely available book for those interested in becoming crime analysts, focusing on learning statistics without delving too deeply into mathematics. Moreover, this book emphasizes practical applications by utilizing R for data analysis, ensuring students can develop relevant skills beyond the university. I hope that students can easily follow the instructions in this book and replicate the same outcomes using the provided data. This practical experience will demonstrate the value of statistics and R, ideally inspiring students to further their learning in these areas.

Since Facebook released React as an open-source software library for front-end programming in 2013, React has gain popularity quickly. Although there are other frameworks or libraries, React is considered a programmer-friendly JavaScript library using the functional programming approach for the front-end web application development. Teaching and learning React can provide training in Functional Programming, Software Engineering Principles, and the Event-Driven Programming Paradigm. The ultimate goal of this eTextbook is to provide a timely support for teaching the state-of-the-art technology as the React ecosystem evolves. In this eTextbook, the prerequisite concepts about HTML/CSS, JavaScript, and Bootstrap/React-Bootstrap are introduced first, followed by the main React language features. Finally, the Software Engineering Principles are introduced from the design, development, to debugging and maintenance. The main objectives are threefold: (1) provide concepts about JavaScript Programming, (2) introduce the concepts of modularity, functional programming, and (3) teach the concept of reusable User Interface (UI) as the front-end of modern model-view-controller (MVC) web applications. Although learning other technologies in the React ecosystem is imminent, it is the hope that this book paves the groundwork for the future learning and growing in the field of modern UI development.

This book contains two parts, the first is designed to be used in an introductory programming course for students looking to learn Python, without having any prior experience with programming. Basic programming concepts are discussed, explained, and illustrated with a Python program. Ample programming questions are provided for practice. The second part of the book utilizes machine-learning concepts and statistics to accomplish data-driven resolutions. Python programs are provided to apply scientific computing to conclude statistically driven results.

This book is intended as an open educational resource for beginning journalism students. It contains information on such topics as the First Amendment, 5 Ws (and H), the inverted pyramid, headlines and subheads, AP and in-house style, writing and editing exercises, and guidance on strategies for covering various stories and/or events. This book essentially replicates the structure of the author’s journalism classes, which are writing-intensive classes. As such, it focuses upon helping student writers begin working on reasonably serious, campus-level journalism assignments as quickly and effectively as possible. The goal is to submit stories, photos, and occasionally video to a university newspaper for publication, all the while following professional standards related to accuracy, clarity, grammar, and AP style.
